Description

Technical Field

[0001] The utility model belongs to the field of ultrafine yttrium oxide powder preparation, in particular to a decomposition device for ultrafine yttrium oxide powder preparation. Background Art

[0002] The main function of the ultrafine yttrium oxide powder preparation and decomposition device is to decompose or heat-treat raw materials, such as yttrium precursors, such as yttrium organic salts or yttrium chlorides, under high temperature conditions to form yttrium oxide.

[0003] In the preparation of ultrafine yttrium oxide powder, the commonly used decomposition devices are mostly high-temperature heating decomposition. First, the raw material is placed in a reaction tube, and then the reaction tube is placed in a heating furnace. Heat is generated by the operation of the heating point on one side of the heating furnace, and the heat is transferred to the reaction tube. The heat is conducted through the reaction tube to transfer the heat to the raw material, and then the raw material will be affected by the high temperature, decompose and react to generate yttrium oxide, so that it is convenient to obtain yttrium oxide powder later. However, in actual use, when the raw material is heated and decomposed into yttrium oxide, since the heating position of the heating furnace is fixed, its heating point will not change during the later heating. If only one position is heated and the raw material is heated and decomposed in combination with heat conduction, uneven heating is very likely to occur, which will reduce the decomposition quality.

[0025] like Figure 1-5 As shown, the raw materials can be placed through the reaction tube body 21, and the tube cover 22 can seal the reaction tube body 21. The reaction tube body 21 extends to the inner cavity of the heating box 11 through the through hole at the top of the heating box 11, and the bottom of the heating box 11 is in contact with the transmission disk 26. The heating box 11 provides space for high-temperature decomposition, and then the high-temperature electric heating tube 12 is operated to generate high temperature, which is transferred to the reaction tube body 21. The reaction tube body 21 transfers heat to the raw materials inside the reaction tube body 21, and then the raw materials inside the reaction tube body 21 are affected by the high-temperature heat, thereby causing a decomposition reaction. During the high-temperature decomposition process, the transmission is driven by the output shaft of the second motor 25. The disk 26 rotates.

[0026] Example 2

[0027] Reference Figure 1 、 2 , 4 and 5 are the second embodiment of the present utility model, which is based on the previous embodiment.

[0028] In this embodiment, the cooling unit 3 includes a protective cover 31, the inner cavity of the protective cover 31 is provided with a centrifugal fan 32, both sides of the centrifugal fan 32 are connected with connecting pipes 33, and the top of the centrifugal fan 32 is connected with an air intake pipe 34, and the surface of the air intake pipe 34 is provided with an ice cylinder 35.

[0029] The back of the protective cover 31 is fixedly connected to the front of the heating box 11, the inner cavities of the exhaust pipe 13 and the air inlet pipe 34 are fixedly connected with interception nets, the top of the ice cylinder 35 is connected with a connecting pipe, and the top of the connecting pipe is movably connected with a round cover, and the inner cavity of the ice cylinder 35 is provided with ice cubes.

[0030] A microcontroller 4 is fixedly connected to the upper end of the front side of the heating unit 1, and the microcontroller 4 is an ESP32 series single-chip microcomputer. A solenoid valve is provided on the surface of the exhaust pipe 13. The output end of the microcontroller 4 is connected to the high-temperature electric heating tube 12 and the input end of the solenoid valve. The input ends of the first motor 23, the second motor 25 and the centrifugal fan 32 are all connected to the output end of the microcontroller 4, and the high-temperature electric heating tube 12 is a FeCrAl electric heating tube.

[0031] like Figure 1 、 2 As shown in Figures 4 and 5, ice cubes can be injected into the inner cavity of the ice cylinder 35 through the connecting pipe to facilitate the subsequent cooling operation. The microcontroller 4 and the centrifugal fan 32 are connected to the solenoid valve. When the microcontroller 4 turns on the centrifugal fan 32 and the solenoid valve on the surface of the exhaust pipe 13, the centrifugal fan 32 can operate to transmit the external airflow to the inner cavity of the air inlet pipe 34. The interception net in the inner cavity of the air inlet pipe 34 can intercept external impurities, and the airflow entering the inner cavity of the air inlet pipe 34 can be cooled by the ice cylinder 35. The cooled airflow will be transmitted to the inner cavity of the heating box 11 through the protective cover 31 and the connecting pipe 33, so that the cold airflow can quickly cool down the reaction tube body 21 and the raw materials therein, and the heat inside the heating box 11 will be discharged through the exhaust pipe 13, thereby achieving rapid cooling, thereby preventing the raw materials from continuing to react and decompose.

[0032] Example 3

[0033] Reference Figure 1-4 , which is the third embodiment of the present utility model, is based on the first two embodiments.

[0034] In this embodiment, a sealing bearing 221 is provided on the surface of the tube cover 22 . The tube cover 22 is located in the inner cavity of the through hole, and the sealing bearing 221 contacts the inner wall of the through hole.

[0035] The bottom of the tube cover 22 is fixedly connected to a threaded barrel 222 , which extends to the inner cavity of the reaction tube body 21 and is threadedly connected to the inner cavity of the reaction tube body 21 . The auger 24 is located in the inner cavity of the reaction tube body 21 and is movably connected to the inner cavity of the reaction tube body 21 .

[0036] Limit rods 211 are fixedly connected to both sides of the bottom of the reaction tube body 21, and limit holes 261 are opened on both sides of the top of the transmission plate 26. The bottom of the limit rod 211 extends to the inner cavity of the limit hole 261 and is movably connected to the inner cavity of the limit hole 261.

[0037] like Figure 1-4 As shown, by aligning the threaded barrel 222 with the feed port at the top of the reaction tube body 21, the threaded barrel 222 can be rotated to gradually enter the inner cavity of the heating box 11, thereby realizing the closure of the heating box 11. When the reaction tube body 21 enters the inner cavity of the heating box 11, the reaction tube body 21 will pass through the inner cavity of the through hole, and the reaction tube body 21 and the tube cover 22 will enter the inner cavity of the through hole, and the tube cover 22 will drive the sealing bearing 221 to contact the inner wall of the through hole, thereby realizing the closure without affecting the movement of the reaction tube body 21 and the tube cover 22. After the reaction tube body 21 enters the inner cavity of the heating box 11, it drives the limiting rod 211 to enter the inner cavity of the limiting hole 261, thereby realizing the connection and limiting of the reaction tube body 21 and the transmission disk 26, so that the transmission disk 26 can drive the reaction tube body 21 to rotate synchronously in the later stage.

[0038] When in use, first, the raw materials are placed in the inner cavity of the reaction tube body 21, and then the auger 24 is driven to enter the inner cavity of the reaction tube body 21 through the tube cover 22, and the threaded barrel 222 is aligned with the feed port at the top of the reaction tube body 21. By rotating the tube cover 22, the tube cover 22 drives the threaded barrel 222 to rotate synchronously. Since the threaded barrel 222 is threadedly connected to the reaction tube body 21, the threaded barrel 222 will gradually enter the inner cavity of the heating box 11, thereby achieving the sealing of the heating box 11. After that, the heating box 11 is driven by the reaction tube body 21 to enter the through hole at the top of the heating box 11, and then the heating box 11 extends through the through hole to the heating box 11. The inner cavity of the box 11, and the limiting rod 211 at the bottom of the heating box 11 will enter the inner cavity of the limiting hole 261 at the top of the transmission disk 26, thereby realizing the connection between the transmission disk 26 and the reaction tube body 21, and then the signal is transmitted to the high-temperature electric heating tube 12 through the microcontroller 4. The high-temperature electric heating tube 12 will operate to generate high temperature, and the high temperature will be transferred to the reaction tube body 21. The reaction tube body 21 will transfer heat to the raw materials inside the reaction tube body 21, thereby allowing the raw materials inside the reaction tube body 21 to be affected by the high temperature heat, thereby causing a decomposition reaction. During the high-temperature decomposition process, the second motor 25 and the first motor 23 are turned on by the microcontroller 4. The output shaft of the second motor 25 drives the transmission disc 26 to rotate. Since the transmission disc 26 is connected to the heating box 11, the transmission disc 26 can drive the reaction tube body 21 to rotate and synchronize the raw materials therein during its rotation, thereby changing the heating direction. At the same time, the output shaft of the first motor 23 drives the auger 24 to rotate, so that the auger 24 can stir the raw materials inside the reaction tube body 21 and drive the raw materials inside the reaction tube body 21 to move up and down, thereby making the raw materials inside the reaction tube body 21 evenly heated, thereby improving the quality of high-temperature decomposition. After the high-temperature decomposition is completed, the centrifugal fan is turned on by the microcontroller 4. The electromagnetic valves on the surfaces of 32 and the exhaust pipe 13 can make the centrifugal fan 32 operate and the exhaust pipe 13 is in an unobstructed state. The operation of the centrifugal fan 32 can transmit the external airflow to the inner cavity of the air inlet pipe 34, and the airflow entering the inner cavity of the air inlet pipe 34 is cooled by the ice cylinder 35. The cooled airflow will be transmitted to the inner cavity of the heating box 11 through the protective cover 31 and the connecting pipe 33, so that the cold airflow can quickly cool down the reaction tube body 21 and the raw materials therein, and the heat inside the heating box 11 will be discharged through the exhaust pipe 13, thereby achieving rapid cooling, thereby preventing the raw materials from continuing to react and decompose, affecting the decomposition quality of the raw materials.
